Performing a Synology DiskStation Migration – A How To Guide
I recently added a DS1815+ to my home lab environment and wanted to migrate my DS1512+ RAID6 configuration to this new DiskStation.
I wanted to do this without a lot of hassle and without losing any of my data on this array.
So, I set out to perform a Synology DiskStation Migration. Synology has a very basic knowledge base article on this topic but the lack of detail doesn’t exactly instill a lot of confidence that it’s going to work. I recommend looking it over mostly for the 1.5 – Can I perform a migration with my DiskStation section – as only certain migration directions are supported. (ie you can’t go from a 5-bay model to a 2-bay model)

Using the info I gathered from that I performed the following 13 steps to complete my Synology DiskStation Migration.
1. Make a full backup of any critical data
Remember, RAID is not a backup. If you can’t stand to lose something, back it up first! Use an external drive, another Synology unit – whatever you can. I didn’t lose any data on my migration, but things can and do sometimes go wrong. Use the Backup & Replication section of the DSM to perform a backup of any data you can’t live without!
2. Ensure you are running the latest available version of DSM
When you load up your new DiskStation, it will be on the latest version of DSM. So, you need to make sure your current DiskStation is also on the latest version of DSM to ensure a silky smooth DiskStation migration! Use the DSM Update section of the Control Panel to make sure you are running the latest version of DSM.
You can get the latest version of DSM for you DiskStation from the Synology Download Center.
3. Backup your DSM configuration
If you’re like me, you likely have your DiskStation tweaked with a lot of settings to suit your environment. Use the Configuration Backup section of the Control Panel to back these up to an external location.
4. Shutdown your DiskStation
OK, our data is backed up, our configuration is backed up, and we are running the latest version of DSM. Time to shut our old DiskStation off!
5. Prep work area for old DiskStation and new DiskStation
You’re going to need some workspace to get these drives transferred, so get your orginal DiskStation and new DiskStation together. Both units should be powered off and disconnected for this.
6. Identify drive order – IMPORTANT!
You must migrate the drives to the same drive location bays. They can be hard to see so I’ve highligted them with red circles in the picture below. So, when you pull a drive out of bay #1 on the original unit, it must go into bay #1 of the new unit!
7. Migrate hard drives from old DiskStation to new DiskStation
Grab a screwdriver and start swapping. In my case, the drive caddies were not interchangeable so I had to dismount and remount the drives into the new caddies.
8. Connect up new DiskStation and locate with Synology Assistant
OK, connect up and turn on your new DiskStation. Then, from your PC fire up the Synology Assistant which will find your new DiskStation. If everything went well you should see your new NICs displaying Status: Migratable
If you don’t have Synology Assistant installed you can get it from the Synology Download Center.
9. Initiate the DSM setup wizard
Double-click on one of your migratable DiskStation links. (Note in the example I have four because the DS1815+ has four NICs – it doesn’t matter which one you double-click). The Welcome to your DiskStation wizard for DSM setup will open.
10. Ensure you select the appropriate installation type
There are two choices, one of which can result in potential loss. Make sure you choose the appropriate one. In my case, I wanted to keep everything exactly the same.
11. Install the latest DSM version for your new DiskStation model
If you haven’t already downloaded the DSM for your new DiskStation you should do so now. You will need to reference it on this part of the install. You can get the appropriate DSM from the Synology Download Center.
12. Configure admin password
13. Complete DSM install and enjoy your new DiskStation!
In my experience this worked perfectly. My RAID6 was completely intact and all Synology settings were identical. I had to setup the new NICs and I was done.
Synology advises that certain features are not able to transfer like Auto-Block settings and Mail Station settings. So, make sure to review the knowledge base article here: How to Migrate Between Synology DiskStations for all the limitations.
